It's funny when you think of it. Here, we're used to the snow & cold during winter. I don't know how I could function at 100° & high humidity. It's all relative to what you're used to.
I hear you I lived in the Northeast most of my life I did live in Dallas for 10 years and it was a nightmare and just about killed me. I spent as much time as I could somewhere on the Gulf of Mexico for the breeze was always blowing and it was bearable if you stayed out of the sun.
I want to curl up and die when I see pictures of 100 plus breeze and say there's no way I could work out it and it all day long like those guys do. I can be outside all day long and 20 below zero LOL
